The coils l/-l are not included in circuit because their circuit connections are new open between the contact 28 and the armature leaf l?, Consequently, electromagnet eectively is energized` by inclusion of its line coils 13 in the circuit, and said magnet attracts its armature 15. .bis the armature moves toward the magnet i poles, its contact leaf l? engages contact 28, so effecting connection. of the differential coils le with the line, in parallel with coils lid, the circuit connections being from line terminal. 36 by wire 39, coils lll, wire 43, contact 2S, and armature 'leaf l, to limb 2O the contact trame and thence by back contact wire 4t2 lto the opposite'ternal 37, f'llhe differential action of the coils 13-13 and leill substantially and etlectively deenergizes the magnet l5, but the momentum o' the armature carries the s ture l5 is quickly retracted by its spring, 27,` ,y

restoring the parts to initial positidn for anot ier cycle of operations.

l nnd that where the magnet is effectively '1 uenergized by differential connection of ne complete breaking of the energized cir-v cuit, no spark at the .circuit breaking terminal loccurs the break, even where high v l il@ volts, is employed. Furthe breaking ci the circuit,

dining' the inagframe i8, Jhas completing theinterior conand circuit controlling del? farther upward, so that its action two windings as a condition precedent to.

net, by a differentially connected coil is advantageous in producing a very quick-acting vibrator movement, and the series connec.

tion oft thediderential coils in local nonenergized circuit reduces the inductive iect of the device in the line.

lt will be observed that the specic construct-ion disclosed is of simple, compact,

and mechanically ellicient form, features of which may hereinafter be claimed for their special advantage, but it will be apparent to those skilled in the art that many changes in the construction and arrangement might be made without departure from the broader aspects of my invention and within the scope of the appended claims.

W hat l claim. is:

1. ln an electro-responsive vibrator, the combination of a magnet having coils that magnetically oppose each other, suitable cir-- cuit connections normally including one of said coils, an armature, and Contact devices actuated by said armature to establish circuit connections for the other coil and subsequently to break the circuit comiections tor both saidcoils'.

2. ln an electro-responsive vibrator, the combination of an electromagnet having windings that magnetically oppose each other, a normally closed Contact device, a normally open Contact device, circuit connections for one ot said windings, normally including the closed contact device, and closed thereby, circuit connections for the other said winding including both said contact devices, andlnormally opened by. the open Contact device, and meansresponsive to uni-directional movementoi said arniature irst to close the normally open contact device and subsequently open the nor- `mally closed contact device.

3. ln an electroresponsive vibrator, the combination of an electro-magnet having windings that magnetically oppose each other, an armature having a contact leaf, a contact frame pivoted for movement by the armature leaf, and circuit connections including a normally open contact device local to the connections of one winding and closable by the armature leaf, and a normally closed contact device common to the connections of both opened by armature-impelled movement of the contact frame.

4.-. ln an electro-responsive vibrator, the combination ofv an electromagnet having windings that magnetically' oppose each other, a pivoted armature therefor, a contact frame pivoted coaxially with the armature, a lined contact for one end of' said iframe, contact for the other end of said trame movable with the armature to close a circuit and thereafter move the frame, circuit connections for one winding including both the normally opened and the normally lclosed windings arrangedy to be f goe-eme 3 contacts, .and circuit connections for he einer vinding inciuding only the nermuiiy cieseei contacts.
